On December 14, 2011, DynaVox Systems LLC (the " Borrower "), DynaVox
Intermediate LLC, DynaVox Services Inc., Blink-Twice LLC, Mayer-Johnson LLC,
DynaVox International Holdings Inc., and Eye Response Technologies, Inc. (all of
which are subsidiaries of DynaVox Inc. (the " Company ")) entered into the
Fourth Amendment to Credit Agreement (the " Amendment ") with GE Business
Financial Services Inc., for itself as a lender and as agent for the several
financial institutions from time to time party to the Third Amended and Restated
Credit Agreement dated as of June 23, 2008, as amended, modified, restated or
otherwise supplemented from time to time, and such other lenders signatories to
the Amendment.

The Amendment (1) modifies the calculation of the ratios of net senior debt to
adjusted EBITDA and net total debt to adjusted EBITDA enabling the Borrower to
utilize cash and cash equivalents of up to $5.0 million to reduce total debt and
senior debt, to derive net senior debt and net total debt without the imposition
of additional conditions or requirements; and (2) enables the Borrower to make a
restricted payment of a maximum of $5.0 million in the aggregate to the Company
to repurchase shares of its equity interests provided that before and after
giving effect to such restricted payment, no event of default shall have
occurred and be continuing. Prior to any repurchase of its shares, the Company
intends to seek approval from its Board of Directors. No such approval has been
sought or received at this time.

Certain of the lenders under the Amendment, or their affiliates, have provided,
and may in the future from time to time provide, certain commercial and
investment banking, financial advisory and other services in the ordinary course
of business for the Company and its subsidiaries, for which they have in the
past and may in the future receive customary fees and commissions.
